Friday, August 12, 2016

[font size=3]Washington, DC— Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as “chemtrails” or “covert geoengineering,” concludes a new study from Carnegie Science, University of California Irvine, and the nonprofit organization Near Zero.

Some groups and individuals erroneously believe that the long-lasting condensation trails, or contrails, left behind aircraft are evidence of a secret large-scale spraying program. They call these imagined features “chemtrails.” Adherents of this conspiracy theory sometimes attribute this alleged spraying to the government and sometimes to industry.

The authors of this study, including Carnegie’s Ken Caldeira, conducted a survey of the world’s leading atmospheric scientists, who categorically rejected the existence of a secret spraying program. The team’s findings, published by Environmental Research Letters, are based on a survey of two groups of experts: atmospheric chemists who specialize in condensation trails and geochemists working on atmospheric deposition of dust and pollution.

…

“Despite the persistence of erroneous theories about atmospheric chemical spraying programs, until now there were no peer-reviewed academic studies showing that what some people think are ‘chemtrails’ are just ordinary contrails, which are becoming more abundant as air travel expands. Also, it is possible that climate change is causing contrails to persist for longer periods than they used to.” Caldeira said. “I felt it was important to definitively show what real experts in contrails and aerosols think. We might not convince die-hard believers that their beloved secret spraying program is just a paranoid fantasy, but hopefully their friends will accept the facts.” [/font][/font]

1. In other news, bear shits in woods and water is wet.

2. Exactly!

Beat me to it!

5. and water is wet.

Not in the upper atmosphere! It's a CHEMTRAIL!!!!!!!!





I remember some article (actually debunking chemtrails) beginning with talking about "mysterious vapor trails across the sky...." There's nothing fucking "mysterious" about them! We know exactly what they are and where they come from.

3. Gubbermint shills!...

What would they know?... (I suppose tag is needed these days)

4. What? Say it ain't so!!

Sadly, no amount of explanation will satisfy these nutters.

6. Earlier this year, I was trying to make time-lapse videos of contrails

... so I started tracking NOAA's "contrail forecast" page which was based on the atmospheric conditions that are known to produce long-lasting contrails. I was only able to track a few weeks before the page stopped updating for some reason, but what I found was that it was about 80% accurate when it predicted I should see some, and I didn't see anything except very short ones when it predicted none.

7. Thanks!

I will pass the URL along to a friend who somewhat reluctantly has accepted my scientific explanations…
